To begin with, Sean Patrick Flannery is a legit BJJ blackbelt and a good actor. Seeing that this movie was made by folks who understand what Jiu-jitsu is, it was very pleasant to watch. The storyline was pretty good too. Definitely one of my favorite martial arts movies of all time. And Renzo Gracie is awesome, so it was super cool to see him, as SPF is a blackbelt under Sean Williams who is a Renzo blackbelt. Then again, coming from a Renzo lineage myself, may just be a bit biased lol.
